If the length of the major axis of the ellipse is times the length of the minor axis, its eccentricity is
Explanation for the correct option:
The equation of the ellipse is .
The length of the major axis can be given by .
The length of the major axis can be given by .
Thus,
.
Therefore the eccentricity of the ellipse can be given by,
Put .
Hence, option (D) is the correct answer.
